Hi,

since I am just getting acquainted with CAS I am certain that my issue is 
configuration or concept related, so first of all I would like to seek the 
guidance of the community on how to properly configure the stack the way I 
thought so, if that is possible at all.

I started out with CAS 5.0.0 using the Maven overlay and configured the 
Trusted authentication webflow, since Apache handles the authentication in 
a standardized way throughout the company. The username gets resolved, the 
login works on the /cas-login page.

Next I wanted to extend the platform with attribute resolution, but 
apparently this part is not working. 

I created a simple MySQL *users *table in the *cas* database like the 
following:

+--------+------------+-----------+----------------------------+
| uid    | first_name | last_name | email                      |
+--------+------------+-----------+----------------------------+
| mgabri | Mate       | Gabri     | mate.gabri@[obscured]      |
+--------+------------+-----------+----------------------------+

The relecant cas.properties settings are the following, which may be the 
first source of error:

cas.authn.attributeRepository.jdbc.singleRow=true
cas.authn.attributeRepository.jdbc.requireAllAttributes=true

cas.authn.attributeRepository.jdbc.sql=SELECT * FROM users WHERE {0}
cas.authn.attributeRepository.jdbc.username=uid
cas.authn.attributeRepository.jdbc.url=[obscured]
cas.authn.attributeRepository.jdbc.driverClass=com.mysql.cj.jdbc.Driver
cas.authn.attributeRepository.jdbc.user=[obscured]
cas.authn.attributeRepository.jdbc.password=[obscured]

In the logs I can catch the following lines:

Dec  5 11:06:31 [obscured] CAS: 
PrincipalBearingCredentialsAuthenticationHandler successfully authenticated 
mgabri
Dec  5 11:06:31 [obscured] CAS: Executing prepared SQL query
Dec  5 11:06:31 [obscured] CAS: Executing prepared SQL statement [SELECT * 
FROM users WHERE uid = ?]
Dec  5 11:06:31 [obscured] CAS: Fetching JDBC Connection from DataSource
Dec  5 11:06:32 [obscured] CAS: Recovering From Exception thrown by 
'org.apereo.services.persondir.support.jdbc.SingleRowJdbcPersonAttributeDao@431b08dc'
Dec  5 11:06:32 [obscured] CAS: Authenticated principal [mgabri] and 
attributes {} with credentials [mgabri].

As you can see the *SingleRowJdbcPersonAttributeDao *is recovering from an 
exception, but I was not able to figure out a way to have more insight in 
what is really happening. Unfortunately I am not familiar with Java 
applications at all so it is a bit hard for me to even start to look for 
solution.

I would like to humbly ask the community to provide me some guidance on how 
to proceed or enlighten me that what I want to achieve is possible at all.

I have attached the pom.xml since that is a bit long.

Kind regards,
Mate
